It would, but usually Superman is very Libertarian in his approach. See, this is part of my view on the tech. It's not that different than the K-tech issue. Superman, when it comes to world politics, keeps out of it. He doesn't pick winners and losers, no matter how a situation in any particular country offends him. To him, there is in fact a higher ideal than just saving lives. If he didn't think that he wouldn't be letting all these people around the world die every day at the hands of corrupt and evil regimes. He doesn't stop all that killing, raping and torture because he can't set himself up as the ultimate arbiter of things that were part of humankind from the start. He would essentially taking away freedom and setting himself up as king. It's why QUEST FOR PEACE doesn't work. Mankind created nuclear weapons and Mankind needs to sort that out.
But when it comes to things that are out of the ordinary, when it's meta human or extraterrestrial, then it falls into his lap. Let's put it this way... An Earthquake happens in Iran, he sticks around to help the wounded as much as he can, but he isn't staying to overthrow the government, even if in the long run the government is a bigger problem for the people of Iran than the Earthquake was. Frankly, I think that beyond even mere crime fighting, that's what Superman wants to spend his time doing. Helping when accidents and disasters strike as to be a symbol of what we all should do everyday. It's just all these freaks, monsters and super villains keep popping up.

I think you are failing to see that moral ideals are fine but putting them into action is not always clear. You take the advantages that the K-tech would bring as a given and lowball the possible/inevitable fallout. I think that Superman is, like it or not, an agent of the status quo, who, lets remember would have a personal stake and emotions attached to these particular circumstances. Sorry, but I just don't feel there is a lot of legitimacy to the idea that he would allow that paradigm shifting tech to just be studied and used willy nilly without considering the negative consequences. As for his body... Uh, he could make arrangements of fail safes or what have you, but frankly that feels like you are splitting hairs here for the sake of it.
